It's not getting any better…

The more I delve into my research, the more issues I discover… the more decisions I would need to make. Frustration is the right word to describe the normal trend I would have to be complacent with… for now!!!

The implementation of mesh surface deformation is not an easy task. I'm currently attempting to understand mass spring model and I couldn't seem to embed it into my mesh data.

My options are to look at :

  • H3D and try out its spring effect api but the irregularities of the object surface make it a bit frustrating to deal with.
  • C++ with opengl +openhaptics

It would be easier if I already have the platform on which I could work on. Starting from scratch is not really practical and it is rather time consuming.

Anyway, my plans:

i) Issues I can address outside of lab

  • conversion: OBJ to X3D
  • fix surface irregularities: solid = false
  • understand and implement simple mass spring model
  • compile chainmail prog to be used in H3D

ii) Issues that need to be addressed in the lab

  • testing new models – solve irregularities
  • include haptic spring onto the haptic viewer example

iii) Theory construction

  • anatomical structure
  • tissue material properties
  • ontological structure
  • algorithms and mathematical methods
